摘要：
In this article, MoS2 nanosheets were applied to modify SiO2 nanoparticles to fabricate SiO2-MoS2 core-shell nanoparticles as well-dispersed nanofillers, enhancing the anticorrosive and mechanical performance of oil-based epoxy matrix. The results showed that SiO2 nanoparticles were covered by MoS2 nanosheets. And interestingly, MoS2 nanosheets could act as reinforcing agent of SiO2 to improve the interfacial interaction between epoxy and SiO2 nanoparticles, enhancing the anticorrosive and mechanical properties of the epoxy resin simultaneously. Herein, the SiO2-MoS2/epoxy containing 3 wt.% SiO2-MoS2 exhibited the greatest anticorrosion performance. Besides, the tensile strength (sigma s) and Young's modulus (EY) of SiO2-MoS2/epoxy coatings (3 wt.%) were also remarkable in comparison with pure epoxy and other composites coatings, increased by 68.7% and 46.5%. We believe that the nanocomposite has a promising application in epoxy coatings.
